serve to return the roof to normal position when displneed.

in the operation ol' the device, the root is pliired 1n position withthe iriotion plates 5 5 of the bridge pieces rest-ing on the frictionpreferably of sutlicient strength and number to return the roof tonormal position when displaced. Some of these springs must be set upafter the roof is in plnee; the rest. moy be secured to the enr at anyconvenient time before the roof is put on.

During the bumping and in'rcsponse to other shocks due to ehunge ofvelocity, the roof moves bark nud forth longitudinally and its motion isarrested by the .sprinfs The friction plates 2U ond prevent eonstnntmovement of the roof due to the neeessory iibszoiou of runnin;` ond muybe odinsnol by ifo-ons ol' the serews 2?' to oll'er tlul resistd'o edesired.

Side motion on the port ol' the root' is per'- mitted as the rollers l5slide l'reelv on the journals 14` Thisnnuiou is token op by the springsat the sides ol' the ver in Iltisume manner :is the longitudinal motionis Hnvin f thus deseribed my invrniion. what I cliiim und desire tosecure by het ier Patent is:

1. A ear body and :i rooi'. the hitter in the 40 form of a singlecontinuous strut-ture sepu- -mte from the rar body :uni mounted thereonto move freely in n horizontal diret-tion relotiVely to the enr body.

2. A enr body and o roof. the lntler mounted on the body to moverelatively thereto in any horizontal dirertion.

3. In o enr, n body having upright sides, a roof for the enr bodymounted thereon to move relatively thereto in any horizontnl direetion,n flange on the roof fitting loosely about the. sides to allow motion ofthe roof horizontally in nl! directions and limit such motion.

4. In n eur, u, body having side walls, n roof 55. mounted thereon tomove, relatively to the ear bod und s. )in ono slot connection between t.e ear body nud roof.

5. A car body having side. walls, a roof mounted thereon to moverelatively thereto,

and a pin and slot eonnection between the.

far body and roof whereby the motion ol' the roof relatively to the enrbody is limited and the direction thereof determined.

6. In o enr, a body and a roof, the hitter in .G5 the form of anintegral substantially rigid iegrnl structure, the roof mounted on theefir bodjr to more relotivel; thereto, one

slotted horizontnliy. o member on the other engaging the slot to limitthe motion of the roof relative to the. cor.

S. A enr body nud n roof, eiu'h being nn integrnl sfrueturo, the roofmounted on the eur body to move rolntively thereto, one being; providedwith key-hole slots, :i projection on the other engnging the slots tolimit the moticon ofthe root' relative to the enr.

9. A enr body and nroof. .em-n being n Seperate integral structure, theroof mounted on the cnr body to move relatively thereto nud providedwith substuntinlly horizont-ol slots, and members on the. enr bodyengaging the slots to limit the motion of the roof.

10. A t'or body und o roof, euch being in the form of o separateintegral strut-ture, one slotted horizontally, the other provided with nroller engaging the sides of the slot to support tile roof.

il. A. enr body aid n roof, each being in the form of n separateintegral strueture, one.

sloted horizontnllym he. other provided with roll rf ognyiugr ille sidesof the slots to .supn indi iin* lmo.

A. eur lowly :md o. roof. eat-h being n seperate integral strutture. n.depending tltrnge on the roof outside tbe cnr body, sunto-l lotti.tellyfnnd members on the enr lo ly engaging tb .slots to permit :indlimit motion of the r11-f1.' ylotii'ely to the enr body.

13. A (for body und it roof, ein-h beinga seperate integnd strutture, :idepending,y flange on the rootoutside the enr bodytitting loosely overthe lutter, nnd n `slot and piu eonnet'tion between the flange and theenr body.

i4. A enr body ond o roof, eneh being a sepnrnte integral structure, ndepending llnngge on the roof outside the ear body litt-ing loosely overthe hitter, the tiling@ slotted horizont-oliv, rollers mounted on theear body en oging the slots to permit und limit the motion of the roofrelatively to the car and support n portion of the weight ofthe roof.

1.3, A ear body und e. roof, each being an integral strueture, the roofmounted on the body to move relatively thereto, moans to limit thetraverso of the roof relatively to the enr, miti-frietion means forsupporting the roof, and means for causing a predetermined nmount offriction between the roof and the vor body.

16. A cnr body and a roof, eneb being u sepairute integral st ruelure,the root' mounted on the body to move relatively thereto, und frirtionineens for boeking the relative un tion 'of the two members.

I7. A vul' body und u root', egich being n sepnrnte integral .strueture, the roof mounted ou the body to move relotively thereto, and

l i i Amove relatively thereto, mea-ns for limiting the motion of theroof, means for eheeking the side motion, means for creating apredetermined amount of friction between the roof and the car body,whereby motion of the roof relatively to the car is revented when theear is subjected to slig 1t shocks, but pel'- mitted when the shocksincrease intviolenee to a predetermined limit. v 1 i 2l A ear body, aroof separate therefrom mounted on the car body to move relativelythereto, a flange on the roof fitting loosely over the cnr body topermit motion of the roof relative to the ear, the fla-nge slottedhorizontally, members en the car engaging the slots, and yieldingmembers between the llzmg'e and the car body to take up the relativemotion.

22. A car body, a roof separate therefrom mounted on the' body to moverelatively thereto, a lla-nge on the roof fitting loosely over the carbody to permit motion of the roof relatively to the ear, the flangeslotted horizontally, rollers on the ear engaging the slots, leafsprings between the flange and the ear body to limit the relativemotion, and friction plates on the car body, and coperating frictionplates on the roof.
